public class VelocityNavigation

extends TemplateNavigation

VelocityNavigation. This screen relies on the VelocityPage being set as the default page. The doBuildTemplate() assumes the user has put the template filename in the RunData parameter and set it to the value of the template file to execute. Specialized Navigations screens should extend this class and overide the doBuildTemplate( data , context) method.
